Liquid crystal emulsifying composition for mask pack, method for preparing same, and mask pack containing same {Liquid Crystal Emulsion Composition for Mask Pack, Method for Preparing Same, and Mask Pack Containing Same}

The present invention relates to a liquid crystal emulsifying composition for a mask pack, a method for manufacturing the same, and a mask pack containing the same, and more particularly, it is possible to stably encapsulate in a network structure of porous fibers, thereby improving skin benefits such as wrinkles and whitening in a mask pack. The present invention relates to a liquid crystal emulsion composition for a mask pack containing a liquid crystal emulsion capable of stably supporting a, a preparation method thereof, and a mask pack containing the same.

Recently, various types of cosmetics are sold in the market, but among them, the mask pack is a product type that many consumers are constantly looking for because of its excellent usability and easy moisturizing effect. Although various types of mask packs such as fiber impregnated masks, hydrogel masks, and biocellulose masks have been developed, there are many fiber impregnated mask packs in which a lotion is impregnated into a fiber support due to skin adhesion and instant moisturizing of the skin surface. I'm getting attention.

Products such as a form in which the lotion is impregnated in the fiber support has been developed a mask pack applied to various types of fiber support, such as cotton fibers, natural long fibers, etc. in accordance with consumer demand. However, the mask pack in the form of the fiber support has only a difference in the fiber type, and most of the fiber support is impregnated with a lotion so that there is a limit to the moisturizing effect of the immediate moisture supply form.

In order to overcome this problem, a mask pack having a high functionality has been proposed, but only skin efficacy ingredients were added to the cosmetics, and it was difficult to expect a clear efficacy effect when used in practice.

On the other hand, liquid crystal (liquid crystal) is a semi-crystalline phase showing the intermediate characteristics of the structural characteristics of the liquid and the regular structural characteristics of the solid, has a relatively less molecular mobility than the liquid due to the regular orientation between molecules. For this reason, it has unique characteristics such as scattering of light and showing physical properties of crystallinity.

Recently, it has been found that liquid crystals may be formed by ceramides, cetyl alcohols, stearyl alcohols, cholesterol, nonionic surfactants, and the like, and may contribute to improved stability of skin useful substances. However, in the case of such liquid crystals, if they contain highly oxidizable skin-soluble substances such as retinol, the ability to prevent the oxidation of the substances is poor, which makes it difficult to use them as products.

Liquid crystal emulsion is a liquid crystal embodying a lamellar structure similar to the intercellular lipids of the stratum corneum of the skin with an emulsification method.It is excellent in moisturizing power compared to general emulsions and can transfer skin active ingredients to the skin. It is applied to high functional basic cosmetic products.

In Table 4, in the case of the liquid crystal emulsifier of Comparative Example 3, when the same content as the liquid crystal emulsifier of the present invention was added, a very high level of high viscosity was obtained as the viscosity was 6,000 cps, and it was adjusted to the same viscosity as the composition of Example 1 In the case of 1% by weight in total, a small amount had to be added.

In order to test the stability of the liquid crystal emulsified composition, the composition of Example 1 and Comparative Example 4 was subjected to a test for one month under harsh conditions of 5 ° C., 40 ° C. and 45 ° C., based on 25 ° C., to measure the viscosity. It is shown in Table 5 below.

Temperature 5 ℃ 25 ℃ 40 ℃ 45 ℃ Example 1
(Initial: 2,500 cps) 2,230 cps 2,510 cps 2,500 cps 2,600 cps Comparative Example 4
(Initial: 2,500 cps) 2,300 cps 2,200 cps 1,200 cps 1,000cps

As a result of the experiment, the composition of Example 1 maintained a viscosity in the range of 2,200 ~ 2,600cps even if maintained for one month in harsh conditions.

However, the composition of Comparative Example 4 was not able to maintain the viscosity of the early 2,500cps and the viscosity was unstable, and it was confirmed that the stability was very poor because the viscosity dropped to less than half at 40 and 45 ° C harsh conditions.

In addition, the liquid crystal emulsified particles before and after one month harsh test of the compositions of Example 1 and Comparative Example 4 were photographed with a 400x polarization microscope and shown in FIG. 3. In addition, based on the observation results, particle sharpness and uniformity are shown in Table 6 below on a five-point scale.

As a result of the experiment, before the harsh test, it can be confirmed that the viscosity, the size of the liquid crystal emulsified particles, and the stability of the compositions of Examples and Comparative Examples are similar.

As a result of a severe test for one month, the composition of Example 1 was stable without singularity, while the emulsion of Comparative Example 4 was lowered in viscosity properties and at the same time deteriorated in particle clarity and uniformity due to instability of the liquid crystal emulsified particles. It is found that it is outside the range of particle sizes that are likely to be.

Considering that the shelf life of cosmetics is generally about 2 to 3 years, it is determined that the liquid crystal emulsifying mask pack of the present invention can maintain initial physical properties well within the shelf life of the mask pack of the prior art.

As described above in detail a specific part of the content of the present invention, for those skilled in the art, such a specific description is only a preferred embodiment, which is not limited by the scope of the present invention Will be obvious. Thus, the substantial scope of the present invention will be defined by the appended claims and their equivalents.
